redirection data to stdin

Hi,
I need to send data read from a comm port (com1 for example) to the keyboard output buffer (stdin).

To do this can i simply use the file I/O function, fread and fwrite, specify stdin as stream to use? Or what?
Can anyone help me?

Tanks.

Hmm... Isn't it a bit weird? You want to redirect sth to stdin? I am not used to this kind of manipulation but would not it be more convenient to say that your port comm is stdin instead of faking it?

open() up a descriptor to com port and then dup2() that descriptor to STDIN_FILENO.
